3
x−3
Step-by-step explanation:
Make an equation.
.1 X .5 X n = .25 X n - 30
.05n = .25n - 30
30 = .20n
150 = n
We have
1/2 liter apple juice ---- 1/3 of her glass
1-liter apple juice --- x
x is the number of glass filled with 1 liter

we can obtain equivalent fractions like

the answers are 2/3 and 4/6

ANSWER
The function that the given graph corresponds to is

EXPLANATION
The given graph in the attachment has x-intercepts at

These are the solutions of the polynomial function represented by the given graph.
We can write all these solutions as factors to obtain,

The product of all these factors gives us the function whose graph was drawn.
This implies that,

Therefore the correct answer is option C.
